You can upgrade to the 14.10 release of HCL Informix® or migrate from other database servers to Informix. Upgrading is an in-place migration method that uses your existing hardware and operating system software. Some changes to the Informix database server can affect upgrading from a previous release.
The Informix® Migration Guide describes how to move data manually between databases, servers, and computers.
If you are installing the new version of the database server on another computer or operating system (non-in-place migration), you can use one of several tools and utilities to move data from your current database server.
